We also produce various sizes of section steel, the main production methods are hot rolling, cold rolling, extrusion, forging, cold drawing and so on. Profile products have complex cross-section shape and various specifications. According to the section height, it can be divided into large section steel, A573 Grade 58 carbon structural steel shape, medium and small section steel, H section steel, I section steel (I-section steel), U section steel (channel steel), l section steel (angle steel) and ball flat steel, etc. Profiles are widely used in various sectors of the national economy, such as I-beam is mainly used in building components, bridge manufacturing, ship manufacturing, etc.; channel steel is mainly used in building structures, vehicle manufacturing, etc;
Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.
The common delivery status of A573 Grade 58 carbon structural steel shape, SA516 Gr 70 plate is as follows: 1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point. 2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air). 3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly. 4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.
The quality grade symbols of Q235 steel plate are A, B, C and D respectively. Different grades represent different impact temperatures. A573 Grade 58 carbon structural steel shape, Q235A is not required for impact toughness test; Q235B is required for impact toughness test at room temperature (20 ℃); Q235C is required for impact toughness test at 0 ℃; Q235D is required for impact toughness test at - 20 ℃. For the above-mentioned B, C and D grade steels, Akv ≥27J is required under different temperature requirements. At different impact temperature, the impact value is also different.
